More from Electrical & Electrochemical Characterisation
- Model 1000D Series Multi-potentiostat
The 1000D series is an eight channel potentiostat that can drive eight independent cells or eight working electrodes sharing one reference and counter electrode. Each channel has its own on or off state, potential and sensitivity setting, and channels can sweep or step together with the primary channel.
- Model 800D Series Electrochemical Detector
The 800D series is built for electrochemical detection, monitoring current through a flow cell in liquid chromatography or flow injection analysis. Its low noise circuitry measures down to picoamperes and plots three decades of current scale during a run. The 8x2D models add a bipotentiostat for dual channel work.
- Model 1100D Series Power Potentiostat/Galvanostat
The 1100D series is a power potentiostat and galvanostat for work needing large current and high compliance voltage, such as battery testing, corrosion, electrolysis and electroplating. It uses a four electrode configuration and still resolves current down to tens of picoamperes. The 1140D adds a galvanostat.
